About the only place I remember seeing it used was over 20 years ago, serving as motor mounts on old 1940s/1950s belt drive air handlers at MIT, where the motor was stuck right to the floor.

thanks,

Very interesting device and I can see how these would be useful.  Any idea what the resonance frequency (or the range) is on these?  I've never thought the isolation "pads" did much good -- these look better to me.

Hi Rusty, on the spec page the wording is pretty vague.

Without looking for it again, I think the max recommended deflection was 0.188".

If their load deflection curve is at all linear, selecting the right length might only make them useful for equipment over 800 rpm or so
